SC = Auto:
Commands that are derived internally (command processing in the CFC) are not
subject to switching authority and are therefore always "enabled".
Switching Mode The switching mode determines whether selected interlocking conditions will be acti-
vated or deactivated at the time of the switching operation.
The following switching modes (local) are defined:
• Local commands (SC=LOCAL)
For the 7UM61 the switching authority can be changed between "Interlocked" and
"Non-interlocked" in the operator panel by password or by means of CFC also via
binary input and function key.
The following switching modes (remote) are defined:
• For remote or DIGSI
Zone Controlled / Zone controlled / field interlockings (e.g. via CFC) includes the verification that prede-
Field Interlocking termined switchgear position conditions are satisfied to prevent switching errors (e.g.
disconnector vs. ground switch, ground switch only if no voltage applied) as well as
verification of the state of other mechanical interlocking in the switchgear bay (e.g.
High Voltage compartment doors open against CB closing).

a separate command.
